I find a quick spray of WD 40 gives old windup clocks a new lease of life. Keeps them going till you have time to clean them correctly.

Thanks for that.

WD-40 is probably not suitable for use anywhere in a pressurized aircraft cockpit or passenger cabin due to its VOC content. As others noted WD-40 is formulated to displace moisture from metal surfaces and provide short term corrosion protection. The seat tracks likely use some form of dry film lubrication, which minimizes contamination from loose floor debris.

I believe the type of Lubricants used in then situation you list are MS4 [Silicon type] lubricants and I also remember a type of lubricant under the brand "Chesterton" being used on seat tracks in the past in the cabin.

Riff_Raff and MAC 40612,

Thanks for getting back to me.

FWIW, No fish oil. I have it on good authority (hee hee) that the Primary ingredient is mineral oil, not diesel or JetA, lesser components are proprietary (the part that 'disperses') and the last is just fragrance. Lots of 'counterfeit' and illegal "real" shipments out of the far east.

My wife works at WD and I get all mine for free. I use it for everything in the machine shop because....its free. Its okay as a coolant on the lathe or mill, but there are better things that dont stink up the shop.

I did speak with a maintenance rep from Textron, er Beech, er...whoever makes Citations now; that WD is NOT ALLOWED in the shop area. Why? "because of its 'flammability'."

While it may be combustible, it does NOT support a flame on its own. Next time you're burning leaves/trash spray some on the fire. It will burn, but immediately goes out.

Sorry, I've been gone so long. Solved my tax issues in CA :)

It smells a bit like it, as to a reason I doubt it would be spayed on seat tracks.

I assume a 777 cockpit seat would have rollers on seats that roll on the tracks, any lubricating of the tracks will not be very effective or long term on a jammed roller.

As for WD40, don't see much around in the aviation game - more LPS1, LPS2 & LPS3 with 2 being closer in viscosity to WD40.

I would also assume that the 777 lubrication chart has nothing for seat tracks but would have for rollers if that is what is fitted.

I also think an O2 leak changing the cabin O2 levels very much a bit far fetched, there is just too much air flow for that - unless pilots don't do smelly farts!
